Dion Khodagholy, PhD

Assistant Professor

Dion Khodagholy is an assistant professor in the Department of Electrical Engineering at Columbia University in New York City.  
He received his Master’s degree from the University of Birmingham (UK) in Electronics and Telecommunication Engineering. This was followed by a second Master’s degree in Microelectronics at the Ecole des Mines. He attained his PhD in Microelectronics at the Department of Bioelectronics (BEL) of the Ecole des Mines (France). His postdoctoral research at New York University, Langone Medical Center was focused on large-scale cortical acquisition and analysis.

His research explores the interface of electronics and the brain in the context of both applied and discovery sciences, with the ultimate goal of new innovations in device engineering and neuroscience methods to improve diagnosis and treatment of neuropsychiatric disease.
